Which motor is right for you?

Two types of motor technology exist in the market, one is a Stepper motor and another is a Servo motor. Both technologies are employed to laser engraving machines. What exactly is the difference between these two control approaches? Which one is better for your equipment?

Servo control technology applies a higher quality motor and controller to send command to the motors and utilizes an encoder to feedback location values to the controller, so the motors always verify their positions. This continual link allows the motors to run faster with higher acceleration and speed that the laser engraver can cut or engrave and also you can move the laser carriage to any position and resume working precisely. Adopting the servo control technology, GCC LaserPro provides a completed line of servo-controlled laser engravers that have an exceptional reputation to produce some of the highest 2D and 3D engraving effects with superior accuracy.

Stepper motors means the motor moves step by step. This is an open-loop device without any feedback information. Thus, the motor cannot accelerate too fast or it will miss steps. Furthermore, the carriage cannot be moved freely by hand since the stepper motor does not have position feedback device to track carriages.

The following comparison sheet presents a clear and thorough examination between servo motor and stepper motor.

Remark:

(1) The servo motor provides constant positional feedback to the controller, which corrects any discrepancy between desired and actual position. When told to move 10 inches down and 10 inches right from home position, it would go exactly to (10,10) position as what it is told. The stepper motor applies the open loop communication with the controller, any steps missing would not be automatically corrected and thus accrue poor positional accuracy.

(2) The acceleration would be the crucial factor to decide the throughput of laser engravers instead of the speed value. The acceleration defines how much time the machine takes to reach the maximum speed. One 100ips laser engraver with stepper motor has much lower throughput than one 80ips machine with servo motor because of the acceleration differences. The stepper motors cannot have the high acceleration as the servo motors, due to the excessive high acceleration would lose steps and accuracy.

(3) A laser engraver equipped with a stepper motor have certain speed limitations due to the stepper motor’s poor torque characteristic under high speed movement, and the result is losing steps and precision.

(4) The stepper motor would lose steps and movement accuracy due to resonance of the motor at low speed movement. While cutting through material under very slow speed, any missing step would break the path movement harmony and destroy the cutting quality. The resonance also makes the stepper much noisier than the servo motor.

Which GCC LaserPro laser engraver should I choose?

GCC LaserPro offers customers a full range of laser engraving options, all with complete functionality, including compact and powerful laser engravers, Venus II and C180II, the largest format system, GAIAII, the most popular system, MercuryIII, and Spirit Series, with fantastic engraving speed.

VenusII and C180II are quite suitable for small items, such as stamps, personalized items or desk accessories, while GAIAII with a 51”x 36” working area is perfect for large format piece processing, such as textile or leather cutting. As for MercuryIII and Spirit Series, they all perform well for general non-metal and anodized materials.

How does the laser work?

GCC LaserPro laser engravers uses the most well-known laser tube manufacturer with the greatest reputation, as its laser power source supplier. The CO2 laser beam can etch or cut non-metal and anodized material through sculpturing the material surface with heat. After setting up the graphic from a graphical program, such as Corel Draw, the GCC LaserPro driver can print out and control the laser system to engrave or cut the material exactly as what you set it with Corel Draw and laser driver.

What is the replacement requirement for air filters?

The air blower’s power provided by GCC LaserPro is 0.75kw with airflow 13/15 CMM (50Hz/60Hz).

What memory configurations are available for GCC LaserPro?

16M comes standard.

What is the cutting capability of the GCC LaserPro laser engraver?

The GCC LaserPro laser engraver is good at controlling the motion system and laser driver to achieve cutting of thicker acrylic than any other comparable laser tube wattage.

GCC LaserPro 30watts laser system can cut acrylic 1/2” thick. This is definitely a great advantage of GCC LaserPro laser systems if you are going to use it for cutting jobs. ASK for SAMPLE.

30 watts

1/2” thick acrylic

60 watts

3/4” thick acrylic

100 watts

1” thick acrylic

NOTE: the listed cutting capability of the different laser powers is for reference only and depends on the different acrylic material supply and customer cutting quality requirement.

What kind of software is compatible with the GCC LaserPro laser engraver?

The GCC LaserPro laser system is compatible with Windows-based graphic programs, such as Corel Draw, Adobe Photoshop, Adobe Illustrator, and Auto CAD.

How do I learn to operate GCC LaserPro laser engravers?

Once you have chosen to purchase a GCC LaserPro laser system, we will provide you a user manual, which will guide you through how to unpack the machine, how to install software, and how to operate the software and laser system to make your own laser crafts. In addition, worldwide GCC LaserPro distributors in your area will provide the required training and support when you purchase GCC LaserPro.
